If everything seems to be fine right now on slit lamp and dilated fundus examination, you need not worry. But if it was a blunt trauma, it's better to get your IOP(Intraocular pressure checked every month for next 4 months atleast).
Blurring associated with redness must have been either due to some corneal epithelial defect or uveitis/inflammation. It's difficult to point out at one particular diagnosis based on your description.
